WiFi connectivity issues have been a documented concern for some Dell XPS 13 Plus users. Here's what you should know.
The Hardware
The XPS 13 Plus uses a Killer Wi-Fi 6E (AX1675) adapter, soldered to the motherboard (not replaceable). It supports WiFi 6E, Bluetooth 5.2, and speeds up to 2.4Gbps.
Reported Issues
Users have documented several problems:
- Connection drops: WiFi disconnects unexpectedly, especially after sleep
- Adapter disappearing: WiFi completely vanishes from Windows until reboot
- Intermittent signal: Random loss requiring system restart
- Poor range: Weaker signal compared to other devices
- Bluetooth interference: Both radios share the same module
Causes
Issues may stem from:
- Driver conflicts with Windows
- Aggressive power management settings
- Hardware constraints in the thin chassis
- Killer adapter firmware bugs
Solutions
- Update drivers: Download latest from Dell support
- Update BIOS: Newer versions improve stability
- Disable power saving: In Device Manager, prevent Windows from turning off the adapter
- Reset network: Use Windows network reset feature
- Change router channel: Reduce interference
Current Status (2024+)
Dell has released multiple BIOS and driver updates that significantly improve reliability. Many users report much better performance after updating. However, not all problems are resolved for everyone.
Recommendation
Test WiFi thoroughly during your return window. Consider keeping a USB WiFi adapter as backup if reliable connectivity is critical.
